The missile industry looks for a technology that is able to replace the very successful legacy thermal battery chemistry widely used in missiles and projectiles. Epsilor offers its customers a unique hybrid technology that reaches the power density of thermal batteries (3,000W/kg) along with an extended shelf life of 15 years. The advantage of these innovative batteries lies not only in the modern lithium cell battery, but mainly in the high performance of its Battery Management System (BMS).
Epsilor’s rechargeable Li-Ion batteries offer a high power – high energy density and cost-effective replacement for thermal batteries. Offering design flexibility to meet complex form factors and enabling full system testing during missile service life, Epsilor’s batteries still maintain long operational life cycle, high readiness and zero maintenance.
Following are several major advantages of Lithium batteries over traditional thermal batteries:
- BMS: Li-Ion batteries for missiles have an internal BMS that enables operators and maintainers to communicate with the missile battery, while installed in the platform.
- Rechargeable and multi-use: unlike thermal batteries that can be ignited only once, a Li-Ion battery can be tested, used in a mission simulation and even in several subsequent missions. When even space launchers become multi-mission systems and can be recovered when back from space, a rechargeable space battery is a very reasonable choice.
- Flexible battery form factor: thermal batteries have certain structure constraints – they always have a perfect cylindrical shape. Missile manufacturers often need a battery with a more flexible structure, whether it is a rectangular shape, a non-perfect cylindrical shape or a battery that is distributed in several locations in the platform. Epsilor’s hybrid batteries can provide high power and different voltage rates as if they were thermal batteries, while having the exact shape required.
- Small manufacturing batch: unlike thermal batteries, Li-Ion batteries may be manufactured in small batches and change their shape and size during product life cycle, while maintaining relatively law unit and design pricing.
